摘要
广播设备开发人员通常使用ASSP来实现SDI和DVB-ASI功能,也可以利用PLD,使用PLD中的逻辑和其他嵌入式资源构建所需的各种数字功能,以实现这些接口。使用PLD可以显著降低总成本。某些情况下,在每ASI通道或者每SDI端口的基础上,PLD方案不到ASSP成本的1/10。
While broadcast equipment developers have traditionally used ASSPs for implementing SDI and DVB-ASI functions, these interfaces can also be implemented in programmable logic devices (PLDs), using the logic and other embedded resources available in PLDs to build the required individual digital functions. By using programmable logic instead of ASSPs, broadcast equipment developers can significantly reduce overall costs. In some cases, the programmable logic equivalent can be less than one-tenth of the ASSP cost on a per-ASI channel or per-SDI port basis.
